potassium nitrate:
Molecular formula: KNO3
Molecular weight: 101.10
Standard : GB/T 1918-1998
Properties: it is colorless and tran***rent rhombic crystals or white powder. The relative density is 2.109 and the melting point is at 334℃. It decomposes at 400℃ and turns into potassium nitrite releasing oxygen and then in continuous heat turns into burnt potash. It is highly soluble in water, liquid ammonia and glycerine but insoluble in anhydrous alcohol and diethyl ether. It can not deliquesce in the air. As strong oxidizer, it will burn and explode when meeting with organics releasing irritant gas. If mixed with carbon powder or sulfur, it burns with strong light.
